(3x + 2)(3x + 8)

(3x − 8)(3x − 2)

Answer 1

another perfect square,

Answer 2

since \(16=4^2\), \(9x^2=(3x)^2\) and \(2\times 4\times 3=24\) it is a perfect square, namely \((3x+4)^2\)

Answer 9

to expand these you multiply the 2nd bracket by the first term in first bracket then multiply 2nd by second term in first bracket:

(3x + 4)(3x + 4)
= 3x(3x + 4) + 4(3x + 4)
= 9x^2 + 12x + 12x + 16
= 9x^2 + 24x + 16
